Endoscopic Fusion Surgery is a minimally-invasive spinal surgery that can be used to correct:

Degenerative Disc Disease

Spondylolisthesis

Scoliosis and other disorders of the spine

This method of surgery reduces patient trauma and scarring associated with traditional surgery by minimizing prolonged muscle retraction, incision size and blood loss. The process preserves healthy muscle and soft tissue while reducing post-operative pain and recovery time. Patients are able to leave the hospital sooner, with less pain and can usually return to their normal daily routine within weeks. Endoscopic Fusion Surgery requires the surgeon to insert a camera through a small incision approximately 1cm in length. Dr. Lewin’s method is a combination of traditional and modern techniques to individualize spinal care for each patient, culminating in the least traumatic solution.
